Work out the perimeter

46CM

Step-by-step explanation:

Perimeter = S + S + S + S + S + S + S +S

Perimeter = 9 + 7 + 8 + 5 + 5 + 8 + 2 + 2

Perimeter = 46 cm

The other 4 measurements:

5 is from the other side labelled 5 this is because they are equal.

8 is from the other side labelled 8 this is because they are equal too!

The twos are from the difference between 9 and 7.

HOPE THIS HELPED

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
